IMPROVEMENT IN LAMPS.

TO ALL WHOM IT MAY CONCERN: v

Be it known that I, HENRY H. BOUCHER, of the. borough of Doylestown, county of Bucks, and State of` Pennsylvanie, haveinvented e. new und useful Improvement in Lemps; endl do hereby declare the following to be e clear and 'exact description of the nature thereof, suicient to enable others skilled in the'urt to which invention appnert'ens to`i`ully understand and use the seme, reference being had to -the accompanying dranings, making part of this specification, ininrhich- Vthe some, es long u s the supply is suiicient.

Figure 1 is en elevation.

Figure 2 a. vertical section of my lump.

Figure 3, n. central section of the cock, seenjn figs. 1 and 2, turned ut right ongles.

The nature of my `invention consists in providing a lomp with a. reservoir und adjustable regulator, for the supply of oil, and also with a. safety-.attechmenh to remove any ges which may be generated in the closed reser- Voir, end which, by its easily-provoked expunsibility,'might otherwise be the 'cause of danger or ineffective operation ot' the lamp. l i i By providing kthe upper end of my tube-regulator with o. fun-nel, I'am able to-ill the reservoir-through it, without being obliged to remove it,.and this I propose to do when it may be desirable.

In the drawings, A represents en arm, with a. vertical pivot, a, which may be supported by a. bracket or lamp-stand, or any other suitable ineens. This arm A. has :t reservoir, B, festened to it, the bottom of which opens into a pipo or conduit, Cf At the end of this vpipe is the lump D.

Between the'reservoir and the lemp,.the pipe C is provided with a. cock, G, to open or close the communi# 'cation between B and D. i Y

A tube, Ffopening into the reservoir, neer the top of it, een also he opened or shut by the cock G, und serves the purpose of removing any superfluous gus from the reservoir. I would, in some ceses, prefer to Iintroduce the tube F neer the bottom oi'B, and let it extend upward inside nearly to Vthe top, as the red lines indicete. Itwould not alter the operation, und preserves the symmetry end beeuty of a. goed design.

`The cock G, und its vents g und g', are sol arranged that, in a. position es represented in iig. 2, gis open and g is shut. A n eighth of u. turn would closeg without opening gf); Yone-'quarter of e. turn would close g and. opcng. l l

'lhe tnbefregulntor E may be so constructed as to allow ufunnel to t on-itstop port,

funnel may be one piece. A l

The lamp-body D is provided with inwardscrew-threads d, near itstop, for the purpose of fastening u. Wicktube, burner, die., to it, to completo'the lamp;

The operation of'my lamp is as follows: The tube E is open et both ends, und its vatng or lowering the tube E from'the position inw from the line H accordingly. v Y l The cock being in the'postion as seen in iig. I?.

or the tube and position determines thelevel of the oil in the lamp D. By elehich it is represented, the level of the oil may be changed wthg open, the filling is commenced.V As soon es the duid reaches the'lowcrl end ot' the tube E, the air above that level, enclosed in B, would resist any further-*rise oi' the fluid inside the. reservoir; therefore I give the cock n.' quarter turn, which closes g but opens g', and fill again, until there is no more nir expelled through gf. then turn the cockGnguin tothe position represented in iig. 2, und the lomp is ready for use.

It is evident that the level of the iluid in th Hoving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 1. The combination, with a. lamp, und n. separate oil-reservoir communicating therewith, of the tubular level regulator E, two-wey cock G, und tube F, 'arranged and operntngsubstantinlly as described.

2. The tube E, in combination with an oil-reservoir and un ,escape-cock, substantially as described.

To the above have signed my nume, this eighteenth day of May, 1868.
